A five word question like "How much RAM for N users?" can not be difficult for an expert!

Look how long and convoluted the answer is: https://docs.moodle.org/en/Performance_FAQ#What_hardware_should_I_buy_for_.27n.27_concurrent_users.3F

Hi

What you say is Moodle does not even try to send mail to _some_ users although others in the same situation get mail? A bug in Moodle of that scale is not known to me. There was a confusion recently caused by an upgrade of the PHPMailer in Moodle. See for example: "Moodle 2.9.1 email config for outlook.office365.com" https://moodle.org/mod/forum/discuss.php?d=321521#p1293434.

Try to confirm that PHPMailer is not trying to send mail, see this post "SMTP PHP debug messages disappear" https://moodle.org/mod/forum/discuss.php?d=316222#p1289850.

A wild guess: Check in the database table user, field emailstop. Any pattern?
